DESIGN PHILOSOPHY

I. Design Philosophy and Approach (continued)

To maintain “Precision Bias” requires an advanced bias circuit that must have a very high 
degree of stability under a wide range of temperatures and load conditions. Most amplifier 
bias networks are of such high impedance and poor thermal regulation that at the extremes 
of operation, bias currents are ineffectively controlled. Advanced tracking techniques used in 
the 60.0 result in absolute control of bias currents under all conditions.

The main power supply of the amplifier consists of a 3000VA transformer with independent 
rectifiers to isolate the channels from one another. 184,000 uF of total capacitance provide 
effective filtering of all AC ripple.

These attributes result in an amplifier of such extreme linearity and bandwidth that no overall 
feedback correction is required or used. One advantage of this is a high degree of immunity 
from interactions with loads or cables and a superior transient response. An extremely low 
nonreactive output impedance is maintained well beyond 20,000Hz. the resulting uniform 
damping factor is not commonly found in other designs.

The chassis of the 60.0 is constructed of machined aluminum milled to very close tolerances 
yielding the seamless appearance characteristic of previous products from Coda. As with all 
high-power amplifiers, heat dissipation is important. The 60.0 uses six massive aluminum 
heat sinks without fans for efficient, noiseless and clean thermal relief. The thermal coefficient 
of the 60.0 heat sinks is one of the lowest and most effective in the audio industry.
